The probability that exactly of them say job applicants should follow up within two weeks is 0.2291

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The binary probability distribution can be used to model the given issue.

Assume that X is a binomial random variable with the values n and p, where n is the total number of human resource managers that were randomly chosen and p is the likelihood that the chosen manager will advise job seekers to follow up within two weeks.

total human resource managers were chosen at random, n = 9

The likelihood that the chosen human resources manager will advise job seekers to follow up within two weeks = 57 (0.57)

As we are aware, the probability of "m" successes for a binomial distribution is calculated as -

[tex]P(X=m) = ^{n}C_{m} (p)^{m}(1-p)^{n-m} = \frac{n!}{m! (n-m)!}(p)^{m}(1-p)^{n-m}[/tex]

Using the aforementioned data, we can now calculate the likelihood that exactly 6 of the 9 applications who were chosen will advise job seekers to follow up within two weeks as follows:

n = 9

p = 0.57

m = 6

[tex]P(X=m) = \frac{n!}{m! (n-m)!}(p)^{m}(1-p)^{n-m}[/tex]

[tex]P(X=6) = \frac{9!}{6! (9-6)!}(0.57)^{6}(1-0.57)^{9-6}[/tex]

[tex]= \frac{9!}{6! 3!} (0.57)^{6} (0.43)^{3}[/tex]  = 0.2291 (rounded to 4 decimal places)

Therefore, the probability that exactly of them say job applicants should follow up within two weeks is 0.2291

The missing numbers here are given by 9×(80+7)=(9×80)+(9×7)

What are missing numbers?

Missing numbers are the numbers that got missed in the given series of numbers with similar differences among them. The process of writing the missing numbers is termed as finding similar changes between those numbers and filling their missing values in their specific series and places.

Here, given 9×87=(9×some number)+(another number×7)

Let x and y be the missing numbers.

9×87=(9×x)+(y×7)

We can write 9×87=9×(80+7)

Using distributive property,

9×87=(9×80)+(9×7)

On comparing, we get x=80,y=9.

           The second one is 3,353 divided by 75 =40 R 4

Answer:

Equation of line is given as y = mx + c, where m is the slope and c is the y-intercept.

Since slope is 5, equation is y = 5x + c.

Substitute (2,-4) into the equation to find c.

-4 = 5(2) + c

c = -14

Hence equation of line is y = 5x - 14

0.384  is the chance that joe has to pay the tab at least once by probability.

What is a math illustration of probability?

Every tuesday Joe has beer with 4 friends .

Each have unique token , and the person whose token is drawn pays the tab.

Since , there are Joe and 4 friends , so we have total of 5 persons.

Now, probability that Joe token will be drawn is =  1 / 5            { 1 (Favourable Outcome) \small / 5 (Total Outcome)  }

i.e there is 1/5  = 0.20 probability that Joe token will be drawn and he will pay the tab.

Over the next 3 weeks , we need to find the change that Joe pays the tab exactly one time.

Here we have n = 3 ( weeks ) , and probability of success is p = 0.20

i.e probability that Joe will pay tab (Success)  is p = 0.20  and probability that Joe will not pay tab ( failure ) is 1-p = 0.80.

So we can model it by binomial distribution , as we have only two outcome which are i) Joe pays the tab , ii) Joe do not pay tab.

X ~ B(n=3 , p =0.20)

We need to find P(X=1) , i.e exactly one time Joe pays the tab .

Since, we have approximate that X follows binomial distribution , so we have

f(x) = P(X=x) = \small \binom{n}{x}p^x(1-p)^{n-x}

Hence

  P(X=1) = ( n  1 ) p¹ ( 1 - p)ⁿ⁻¹

             = ( 3  1 ) 0.2¹ ( 1 - 0.2)³⁻¹

             =  3 * 0.2 * 0.8²

We can check this using Pythagoras' theorem.

Explain Pythagoras' theorem?

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship in Euclidean geometry between the three sides of a right triangle. It asserts that the area of the square with the hypotenuse (the side opposite the right angle) equals the sum of the areas of the squares with the other two sides. This theorem may be expressed as an equation linking the lengths of the legs a, b, and the hypotenuse c, which is known as the Pythagorean equation: a² + b² = c²

According to Pythagoras' theorem, as we see a² + b² = c²

6² + 8² = 10², so the photo frame is still a rectangle.

3x≤22.5+1.5

Add up the numbers.

3x≤24

Divide.

x≤8

Answer:

x= 8

Step-by-step explanation:

So this is not as hard as it looks

the aim of this question is to work out what x is

so we need to find x on it's own

therefore we must work on removing the number on the right and to do this we first of all have to get a number that is divisible by 3.

now this is not always the case but I think you can tell from this question that it is obvious.

so what you do first is reverse the -1.5 into a positive and if it was the other way round so positive to a negative

so we do 1.5 + 22.5 which equals to 24

now this is simple division so 24 ÷ 3 = 8

therefore making the answer x = 8

The reflection of the coordinate (-3, 4) over the y-axis is (3, 4).

The Y-coordinates do not change when a point is reflected across the Y-axis. However, the X-coordinates are changed into their opposite signs.

Given the coordinates of the triangles RST as shown below;

R = (-3, 4)

S = (-1, -4)

T = (-4, -2)

If (x, y) for instance is reflected over the y-axis, the resulting coordinate will be (-x, y). Similarly, if the coordinate R (-3, 4) is reflected over the x-axis, the resulting coordinate point will be (3, 4)

Answer:

X=17/24

Step-by-step explanation:

first you need to find common denominators. To find it, you would multiply the denominator of the 1 2/3 and the 2 3/8.8*3=24, which means the denominator is 24. For 1 2/3, we multiplied 3*8 so we also have to do it for 2. The new equation is x+1 16/24=2 3/8. But remember, we still have to multiply 8*3, which means we have to multiply 3*3 too.

New equation:x+1 16/24=2 9/24

The $150 monthly payment on the $3,482.46 credit card loan at 1.55% monthly interest rate gives the number of fewer months it would take to repay the loan if the monthly payment is $200 as 10 months

A monthly interest rate is obtained from an annual interest rate by dividing it by 12.

The monthly payment formula is presented as follows;

[tex] \displaystyle{M = \frac{P \cdot r \cdot (1 + r)^{n} }{ (1 + r)^{n} - 1}} [/tex]

Where;

M = The monthly payments = $150

P = The loan amount = $3,482.46

r = The monthly interest rate = 1.55% = 0.0155

n = The number of periods (monthly payments) = 30

When the monthly payment, M = $150, it takes the career councilor approximately 30 months for the debt to be repaid.

When the monthly payment, M = $200, we have;

[tex]\displaystyle{200 \approx \frac{3482.46 \times 0.0155 \times (1 + 0.0155)^{n} }{ (1 + 0.0155)^{n} - 1}} [/tex]

Which gives;

[tex] \displaystyle{200 \times ((1 + 0.0155)^{n} - 1)= 3482.76 \times 0.0155 \times (1 + 0.0155)^{n}} [/tex]

[tex] \displaystyle{200 \times (1.0155)^{n} - 200 = 53.98278 \times (1.0155)^{n}} [/tex]

[tex]\displaystyle{ 146.017 \times (1.0155)^{n} = 200 }[/tex]

n•ln(1.0155) ≈ ln(1.3697)

[tex] n = \frac{ln(1.3697)}{ln(1.0155)} \approx 20.45[/tex]

Step-by-step explanation:

To make a scientific notation the whole number must be more than 1 and less that 9.9 repeating. To do this, move the decimal however many times it takes to make the whole number (the number before the decimal) more than one and less that 9.9 repeating. For the number 33,900,000, the decimal must be moved 7 times, which is why I added the 7 exponent. Also when making a number into a scientific notation, be sure to add the number after the whole number, placing it after the decimal.
